About Guillaume

I combine my past experience as an engineer in the luxury industry and Nocode development to help project owners and non-technical entrepreneurs launch their 1st functional prototype (MVP) in a few weeks, with rationality and seriousness.

You have a vision, possibly a mockup? I become your teammate to build and launch your app. I act as if we were partners.

The advantage of Nocode and Bubble? Develop quickly (and therefore cheaper) and get custom solutions.

➡️ The faster you test, the faster you get feedback, the faster you adjust, the faster you take off 🚀

➡️ During the first part of my career, I managed complex technical projects, orchestrated teams, optimized costs, met deadlines, and managed budgets from A to Z.
This could be a plus for your application project 😉

➡️ The method:

- We discuss, you explain your vision, your ideas.
- I build a clear and precise specifications document, which we validate together.
- I produce mockups if necessary, a design.
- Are we in sync? I develop your app.
- We test, we correct, we adjust.
- That's it, you can test your app with real users.
- Collect feedback, we adjust the app.
- Are you ready to grow? We discuss the next steps.

➡️ A quickly and well-developed app, even at the MVP stage, reassures your partners, your investors, your clients. And you can start building a user base.
